Inventory management can be tricky.
Unless you sell beer and potato chips on Super Bowl Weekend, you never really know how many – or what kind – of anything you’re going to need at any given time.
Shelved inventory complicates cash flow.
Not enough inventory complicates customer service.
I’ve always tended to err on the side of “I’d rather have it and not need it than need it and not have it.”
However, that may not translate well for trucking parts, with literally thousands of components that can be ordered, which leaves the burden to bare as having what you need when your customers need it.
Most businesses combat overstock by only ordering high volumes of common parts. More niche and unique items are generally either special orders or ordered in low quantity.
